HOW MANY WATTS ARE YOU USING ON YOUR RACE CAR TRAILERS ?? TRYING TO GET A IDEA WHAT TO BUY?
same 7500 Onan in the bus also...but when it is hot out it is just too much trying to cool the family off and run fans, charger outside for the car. Thats why I just went ahead and bought a gen for the trailer. No more issues here.We have a 5500 watt just for the trailer. Powers the inside and outside lights, bottle warmers, laptop, air compressor, and battery charger with no issues. We have also used the 7500 watt Onan on the motorhome to power the trailer but you have to be really careful when using the appliances in the motorhome if everything is going in the trailer also.
I run a Honda EM2200X & run all this & then some. For what your doing you dont have to run out & get a 5500 but sometimes....."Bigger is Better" Depending on the size of the Compressor Etc. If you get a good deal on one it's usually nice to have the xtra power. You never know when ya may need it! Look on Craigslist E-Bay Etc. Some Killer Deals out there if you look!!! Best Of Luck Dude!yes. and laptop?
